Major bootup problem (FIXED)

[mcp555]

EDIT: Problem fixed. Replaced motherboard.

These are the parts I have:
Antec 350W PSU
Abit KD7 (updated BIOS to newest release)
Tbird 1.33 (133) with Vantec Aeroflow
Seagate Barracuda IV 60GB
Kingston PC2700 512MB Valueram
SB Live
Panasonic 16x DVD-ROM
MSI Geforce 4 MX440 8X AGP

This has run flawlessly for months now. A few days ago I opened up the case and used a can of air duster to clean it out with. When I reconnected the system and tried to power it up, it would power on but I could not get it to post.

What works:
1)PSU/PSU fans (power to motherboard ok)
2)Video card/video card fan (The "check video signal" warning on the monitor drops when I turn the system on)
3)CPU HSF
4)Case power LED
5)Optical mouse
6)HD LED (it blinks a couple of times when I power the system on but the HD does not start to read as if it were booting Windows)

What I've tried:
1) Disconnecting the DVD drive
2) Removing the sound card
3) Reconnecting/reseating all cables and cards
4) Switching RAM slots
5) Using a different hard drive

I get no "post" screen on the monitor at all. Also, on my motherboard I have two diagnostic LED's that light up. The green one still comes on and always stayed on when the system worked. I also get a yellow LED now though. Any ideas?

Did something happen to the HS/F?
Do you have another processor to try?

Check the mobo manual and see what the green and yellow lights mean. Also you said "hooked it all back up" maybe you acidently got dust into a sensitive part of the mobo. Or maybe this is a BIG maybe you shocked something.

Oops. Double post.

The HS/F still works fine. I do have another processor to work with. I guess I will try swapping that out over the weekend. I will also try dusting it out again. Maybe some dust got into a critical area. As far as static shock goes, I'm not ruling that out either. In fact that was my first guess. Question is what, if anything, got shocked. I also checked my manual a few nights ago about the LED's. I could not find any mention of them.
